Our ventilation systems are designed bearing in mind the load volume and specific capacity requirements. The ventilation conducts are made of SAE 1020 steel sheets with 2 mms diameter perforations stiffen with transversal ribbing. Depending on the characteristics of the base of the silo, the air conducts can be half round sections, tubes or covered tubes. The centrifuge fans can be used to extract or to blow air in. The superior ventilation is achieved in a natural way with vents or it can be forced with axial extractors.
